Marine pollution comes from waste and brings a solemn issue since the utmost debris in sea urban residential household waste. The family has critical role reducing waste, which can further decrease negative impact on marine life. Meanwhile, education management is still insignificant for children their parents. It necessary to have source of information an early age encourage awareness implemen...

This study proposes a novel process design for lignocellulosic biomass to ethanol conversion with zero waste generation. In comparison traditional bioethanol process, the proposed new not only produces ethanol, but also converts streams into high value-added by-products by undergoing multi-stage refinery steps. The feasibility design, especially additional processing, has been carried out. resu...

Zero waste management is a holistic concept that recognizes both as resource and measure of the inefficiency our modern society. While traditional system considers an ‘end-of-life’ product consumption, zero challenges this notion by recognizing transforms resources in intermediate stage consumption process. In context, most critical aspect creating zero-waste city shifting from linear economic ...

Oil palm (Elaeis guineensis Jacq.) is a productive plant where every part can be utilized. Not only the flesh and kernels of fruit extracted into oil, but by-products produced during production process their waste also processed something useful. One zero waste-based oil processing that being developed at this time use non-productive tree trunks replanting period, namely by taking sap. This res...

Greenhouse gas (GHG) emissions per person from urban waste management activities are greater in sub-Saharan African countries than in other developing countries, and increasing as the population becomes more urbanised (Couth and Trois, 2010). Waste from urban areas across Africa is essentially dumped on the ground with little or no control over the relative liquid and gaseous emissions. The Cle...

This paper presents a two-stage intelligent search algorithm for a two-dimensional strip packing problem without guillotine constraint. In the first stage, a heuristic algorithm is proposed, which is based on a simple scoring rule that selects one rectangle from all rectangles to be packed, for a given space. In the second stage, a local search and a simulated annealing algorithm are combined t...
